To all whom itmay concern:

Be it known that I, FRED W. LEUTHESSER,

' a citizen of the United States, residing at the wall of the radiator an ,valve and having the valve set vertical in order to obtain the full benefit thereof, but is adapted for use and can be used with other species of air-valves.

It is customary to enter the valve into the wall of the radiator, so as to make a tight joint against leakage at the point of attachment of the air-valve to the radiator, and if this joint is broken or the valve turned from its set vertical position the operativeness of the valve will be impaired ordestroyed. It

has been found in practice that unauthorized persons, and articularly children,- will turn the air-valve lliterally or sidewise out of its set position, rendering it ino erative or breaking the joint between the air-valve and the radiatorsufiiciently to cause a leakage, and thus impair or destroy the efliciency of the valve. v

The primary object of the present invention is to insure the maintaining of the airvalve in its. set position and to revent anya lateral or sidewise turning of t e air-valve except by an authorized person; and the inventlon consists in the several parts and combination of, parts hereinafter described, and pointed out 1n the claims as new.

In the drawings, Figure 1 is an elevation of an air-valve and a portion of the wall of the radiator with the wall of the radiator in section and showing the holder or retainer of the invention in position for use; Fig. 2, a top or plan view of the holder or retainer of the invention, showing the two sections thereof united together; Fig. 3, aside elevation of the section of the holder or retainer which interlocks fwith the body of the airvalve; 4, a sectional elevation" of the inopeni taper d terlocki ng section of the holder or retainer shown in'Fig. 3; Fi 5, an end elevation of the-section of the ho der or retainer which is to.be entered into the wall of the radiator; Fig. 6, a top or plan view showing a modification in the section of the holder or retainer which interlocks with the body of the airvalve; Fig. 7, aside elevation of the interlocking section of the holder or retainer shown in Fi 6, and Fig. 8 a sectional elevation of the inter ocking section of the holder or retainer of Fi .6.

- It is not deemed necessary for the understandin of the invention to show a radiatorcoil, an for this reson only awall A of a radiator-coil is shown, it being understood that the radiator-coil can be of any usual and 7e well-known form of construction ada ted to have an air-valve applied thereto. he airvalve shown is of that type havin a body B, containing an usual and wellown ar- 7 ran ement of evices, such as a float, for con- 7 5' trol g the passage of air, such body, as shown, having a neck or extension I; as usual. The body or shell B of the air-valve is entered at'lts lower end into a base O, as usual, such base having on its bottom a wall C, with the usual conduit or passage there through opening into the bottom of the valve and terminating in an end or nipple c, preferably ta ered and having on its exterior a screw-t sad and threaded into a hole. a in the wall of the radiator, so a's to make a tight joint between the end or nipple and the wall of the radiator.

' Air-valves for radiators are generally attachd so as to stand vertical and when in place should be held in their vertical or ad- 'usted position, and for this purpose the holder or retainer of the invention is intend-,

ed. This holder or retainerxconsists of a sec-, 9

tion D, in the shape preferably of aband-or 9 5 rim, which, as shown in Figs! 2, 3, and 4, is of an oval shape and has an oval-shaped hole or d, which may have its walls slightly upwardly, as shown in Fig. 4, and

this section D of the holder or retainer on one ,side has a lug or ea'r d for uniting the section D with its companion section. The comanio'n section E of the holder or retainer is m the form of a solid plug, preferably tapered and 4 havin on its exterior face a vscrew- 10' 5 thread, which enables the plug tobe threaded into ahole a, formed therefor in the wall of the radiator, so as to make a tight, joint between the plug and the wall of the radiator against leakage. The section E has extending from the outer end ofits plug portion a pair of cars or lugs e, between which is an opening or space e, into which is entered the lug or ear d2 Thetwo sections D and E of the holder or retainer are secured together in the construction shown by a screw F, for which pur ose one or both of the ears or lugs E is provi ed with a screw-threaded hole for the passage of the stem of the screw, and, as

shown, the lug or ear (1 is provided with a holef, through which the stem of the screw -F passes, uniting the two sections of the holder or retainer one to theother:

The construction shown in Figs, 6, 7 and 8 illustrates a modification in which the wall or rim of the section D of the holder or retainer 5 is'in the shape of a circle instead of being an other.

' neckd' to enter betweenthe lugs'ore' rs e for. I the holes between theseveral lugs to a ine, af-

pin maEe atight joint.

-it is preferred, and in all cases desirable, that the section-E-should have a taper, forming a plug, in order to insure a tight. joint around the section at its entering-point into the wall of-the radiator.- Q

In use-. the air-valve is fixed .in position on the radiator by entering the hollow nipple or 0 into the wall' of-the radiator, so as to This locates the osition of the air-valve and enables the wor' an or mechanic to properl T locate the place for making the holein t eywall of the radiator :for inserting the section E of the holder or re- 'tainer," andthis-screw threa'ded hole a can} be madebyfthe use ofsuitable tools. Where the holder or retainer s made in two sections, i the section E oanbe entered into the wall of' "the, radiator first, ,and the section D can he" slipped 'over the end I) or other port on of the va ve and brought into position for its lug or ter which the screw'F; can be inserted, uniting the two sections one to the other and locating the holder or retainer in a fixed position .with the, air-valve caught thereby and held against lateral turning or-twisting. Theel'ongated o ening d in the 'wall or rim of the section D a lows of a slight movement end-- -w'ise for adjusting purposes, so as to insure the necessary contact ofthe wall orr-im, with the entered portion of the air-valve to pre vent lateral or side play, and intheconstmic:

scene? 8 this ehdwise movement for ad ustin pur- Iploses is permitted by the elongated 5 0t or ole through which the locking-screw F asses. I

The holder or retainer is preferably made in two sections, as by that arrangement it can be placed in position and be made to engage with the airwalve readily and quickly, and byhavin adjusting means between the two sections 51c relation of the holder or retainer as a whole to the position of the airvalve can be regulated so as to insure a positive retention of the lair-valve in its set or adjusted position and a'gainstlateral or side turning or swing.

What I regard as new, and desire to secure by Letters Patent,is. p I

1. In combination witha radiator having an air-valve screwed thereto, a holder. or retainer for maintaining the air valve its set position, consisting of two sections, one of the. sections being in'the form ofa ring encircling the-valve, and'the other section being in the form of a "plu'gscrew-threaded into the radiator, and a separable connection for aland disengage from the stantially as described. H 2. In combination'with a radiator, an airvalve having a nipple screw-threaded mto the radiator, a holder or retainerfor mainsections being secured to the radiator and the arable connection forthe'two sections, so
